摘要: Micromachined microvalves are held both open and closed electrostatically to maintain uniform gas microflow and improve closure characteristics. A microflow controller containing such a valve is combined with a predetermined restricted flow path. Multiple valve/restrictive flow path combinations are integrated on a binary flow path basis. Single and/or multiple valve actuation provides precise but variable flow control. Temperature and pressure sensors can be integrally included. Various valve and controller configurations, and methods of controlling them and forming them, are disclosed.
